Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the case of a large article such that the load occupies a large part of the loading platform, after unloading the load, it is necessary to move the load back and forth on the loading platform. On the other hand, at a site where labor shortage is a problem, it is required to perform such loading and unloading work of the load in one operation (also referred to as one-man operation, one-op), and there is also a need to reduce the device cost as an accessory of the vehicle.

[0005] However, the loading device described in Patent Document 1 is equipped with a lifting device including a hydraulic pump and a hydraulic electric cylinder, and the device is large-scale. Therefore, the loading device described in Patent Document 1 has a problem of imposing a burden on the device cost.

[0006] Therefore, an object of the present invention is to provide a loading device that can reduce costs with a simple configuration while ensuring the stability of work and reducing the burden on workers.

Means for Solving the Problems

[0007] (1) The loading device of the present invention provided to solve the above-described problems includes a guide portion installed on a loading platform of a vehicle, a carriage portion that moves along the guide portion, and is stored in the carriage portion. And a support portion that stands on the ground and supports the carriage portion by being deployed toward the ground in a state where the carriage portion is moved until it reaches outside the loading platform. It is characterized by that.

[0008] Since the above-described loading device is configured such that the carriage unit moves along the guide unit installed on the loading platform, the load carried on the carriage unit can be placed at the required location on the loading platform along the guide unit. Therefore, for example, even in the case of a large object that occupies a large part of the loading platform, after lifting the load, it can be moved, for example, back and forth on the loading platform. Further, the above-described loading device can support the carriage unit by standing the support unit on the ground by expanding it toward the ground in a state where the carriage unit is moved until it reaches outside the loading platform. Therefore, the above-described loading device can easily transfer the load onto the loading platform via the carriage unit even when loading a heavy load on the loading platform. Accordingly, the above-described loading device can perform the loading and unloading operations in one operation even for heavy loads. Further, since the above-described loading device can store the support unit in the carriage unit, it does not interfere with the load on the loading platform. Furthermore, since the above-described loading device can expand the support unit toward the ground outside the loading platform, the support unit can function as a support leg of the carriage unit during the loading and unloading operations. Therefore, since the above-described loading device does not need to be provided with another drive source, it can be configured with a simple structure, and cost reduction is possible.

[0009] (2) The loading device of the present invention described above is preferably characterized in that the support unit includes a biasing unit that applies a biasing force in a direction from the ground toward the carriage unit in a state where the support unit stands on the ground.

[0010] Even when the support unit is pushed downward (toward the ground side) by the weight of the carriage unit on which the load is loaded and is in an inclined state, the carriage unit is pushed up by the biasing force of the biasing unit. Therefore, the above-described loading device can lift the load to the height of the loading platform without burdening the operator even when a heavy load is loaded on the carriage unit. Here, various biasing means can be used for the biasing unit, but it is desirable to use a damper member or a spring or the like that is inexpensive and does not have a separate drive source.

[0011] (3) The loading device of the present invention described above is characterized in that the support part includes at least one damper member having a cylinder and a piston, and the carriage part includes a rotating part that is rotatably supported with respect to the guide part in a state of protruding outside the loading platform, and a locking part that holds the support part in a state of being pushed downward below the vehicle via the carriage part in a state of protruding outside the loading platform.

[0012] With such a configuration, the loading device described above can hold the damper member provided in the support part by the locking part in a state of being pushed downward below the vehicle via the carriage part. That is, since the loading device described above can hold the damper member in a state of being pushed down by the weight of the carriage part (loaded object), by releasing the locking part, the carriage part can be lifted using the biasing force of the damper member. Therefore, according to the loading device described above, an operator of the loading and unloading work can load the loaded object onto the loading platform with one operation. Further, since the damper member provided in the support part of the loading device described above is composed of a cylinder and a piston, it can be configured without using other drive sources (for example, a motor or a pump). Therefore, the loading device described above can be configured with a simple structure, and cost reduction is possible.

[0013] (4) The loading device of the present invention described above is characterized in that the carriage part includes a gripping part on the protruding end side from the loading platform.

[0014] With such a configuration, the loading device described above can perform operations related to pushing down and lifting the carriage part via the gripping part (for example, an operation handle). Therefore, the loading device described above can improve the operability by the operator. Here, the gripping part is preferably configured to be foldable and storable, for example. Thereby, when the carriage part is moved onto the loading platform, the loading device described above can widen the storage space of the loading platform by folding the gripping part, and can also suppress the gripping part from protruding outside the loading platform.

[0015] (5) The loading device of the present invention described above is characterized in that the carriage part includes a rotation support part for rotating the load mounted on the carriage part.

[0016] With such a configuration, the above-described loading device enables an operator to load a load onto the carriage part without worrying about the loading direction of the load. That is, after loading the load onto the carriage part, the above-described loading device can freely rotate the load via the rotation support part, so that the burden on the operator of reloading the load can be reduced.

[0017] (6) The loading device of the present invention described above is preferably characterized in that an article storage part is provided on one side or both sides in the width direction of the guide part on the loading platform.

[0018] With such a configuration, the above-described loading device can effectively utilize the storage space of the loading platform. Here, examples of the stored items stored in the article storage part include, for example, when the load is equipment (such as agricultural machinery or drones), driving batteries, agricultural chemicals, fertilizers, etc.

[0019] (7) The loading device of the present invention described above is preferably characterized in that the support part is rotatably supported with respect to the carriage part.

[0020] With such a configuration, the above-described loading device can rotate the support part to a predetermined angle (for example, the vertical direction) according to the inclination of the carriage part. Further, the above-described loading device can be stored in the carriage part, for example, by rotating it in the direction along the carriage part.

[0021] (8) The loading device of the present invention described above is preferably characterized in that the load mounted on the carriage part is a drone.

[0022] With such a configuration, the above-described loading device can load a drone used in agricultural operations such as pesticide spraying and fertilizer spraying onto the loading platform of a light truck or the like in one operation. Therefore, the above-described loading device can be easily used and provided at a low price even in fields such as agriculture where there is a shortage of manpower.

Effects of the Invention

[0023] According to the present invention, it is possible to provide a loading device that can reduce the burden on workers, ensure the stability of work, and reduce costs with a simple configuration.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, the loading device 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that each drawing is schematically shown for easy understanding, and it should be noted that the actual shape, size, and arrangement of components may be different. In this embodiment, a light truck is used as the vehicle 2, and a case where a drone (also referred to as drone 3) is loaded as the load 3 will be described. Also, hereinafter, the front-rear direction of the vehicle 2 (loading platform 2A) may be simply described as the front-rear direction, and the width direction of the vehicle 2 (loading platform 2A) may be described as the vehicle width direction. Also, in each drawing, note that the driver's seat, wheels, etc. of the vehicle 2 are omitted, and only the loading platform 2A is drawn.

[0026] As shown in FIG. 1, the loading device 1 includes a guide portion 10, a carriage portion 20, a support portion 30, and the like.

[0027] The guide portion 10 is composed of a pair of rails 11, 11 arranged at intervals in the vehicle width direction (the left-right direction in the drawing). The rails 11, 11 are installed on the loading platform 2A of the vehicle 2 so as to extend along the front-rear direction (the up-down direction in the drawing) of the vehicle 2. The rails 11, 11 are configured to guide the movement of the side frames 21, 21 of the carriage portion 20 described later in the front-rear direction of the vehicle 2. Also, the rails 11, 11 are provided with covers 11A, 11A that cover a part of the side frames 21, 21 so that the side frames 21, 21 do not deviate. Further, on the rear end side of the rails 11, 11, appropriate locking members (not shown) are provided so that the side frames 21, 21 do not fall off.

[0028] As shown in FIGS. 2 and 3, the carriage portion 20 includes a pair of side frames 21, 21 provided at substantially the same interval as the interval between the rails 11, 11. The side frames 21, 21 are formed so as to extend in the front-rear direction (the left-right direction in the drawing) of the carriage portion 20. The rear end sides of the side frames 21, 21 constitute gripping portions 26, 26.

[0029] The side frames 21, 21 are arranged on the rails 11, 11 and can slide on the rails 11, 11. Wheels may be provided on the side frames 21, 21 as required. In this embodiment, the side surfaces and upper surfaces of the side frames 21, 21 are covered by the covers 11A, 11A. Therefore, the side frames 21, 21 are movable in the front-rear direction of the loading platform 2A along the rails 11, 11. That is, the carriage unit 20 is movable in the front-rear direction of the loading platform 2A along the rails 11, 11.

[0030] Also, on the front end side of the side frames 21, 21, a pair of rotating parts 25, 25 are provided which engage with a locking member (not shown) of the rails 11, 11 and are rotatable with respect to the rails 11, 11. Therefore, the side frames 21, 21 can be rotated with respect to the rails 11, 11 and inclined downward (towards the ground side) at the protruding ends protruding outward from the loading platform 2A. Although details will be described later, at this time, the side frames 21, 21 are supposed to tilt against the biasing force of the biasing parts 32, 32 described later.

[0031] Near the center in the front-rear direction of the side frames 21, 21, a pair of cross bars 22A, 22A are bridged in the vehicle width direction. Also, behind the cross bars 22A, 22A, a cross bar 22B is bridged in the vehicle width direction.

[0032] On the cross bars 22A, 22A, a rotation support part 23 for rotatably supporting the load 3 is provided. The rotation support part 23 is configured to be rotatable around a vertical axis with respect to the carriage unit 20 (cross bars 22A, 22A) by an appropriate rotation mechanism (not shown). On the upper surface side of the rotation support part 23, a protrusion part 23A, a lock mechanism 23B, etc. for locking the load 3 are provided. The load 3 transported onto the carriage unit 20 has a part of its main body frame locked to the protrusion part 23A and is fixed by the lock mechanism 23B. Thereby, the dropping of the load 3 from the carriage unit 20 is suppressed.

[0033] FIG. 6 is an explanatory view showing a state in the middle of rotating the load 3 fixed on the rotation support portion 23. The rotation support portion 23 can be provided with fixing means (for example, fixing pins, latches, etc.) for suppressing rotation at an appropriate position as necessary. In the present embodiment, a fixing pin 23C is provided on the rotation support portion 23. Further, a hole is formed in a predetermined position (for example, the front-rear direction) in the rotation axis (not shown) of the rotation support portion 23, and by inserting the fixing pin 23C into the hole, the rotation support portion 23 is fixed at a predetermined position (predetermined angle). In the present embodiment, by inserting the fixing pin 23C along the front-rear direction of the carriage portion 20, the rotation support portion 23 is fixed along the front-rear direction of the carriage portion 20.

[0034] The gripping portions 26, 26 constitute handles that can be gripped and operated by the operator M. The gripping portions 26, 26 may be provided with anti-slip rubber or the like as necessary. The gripping portions 26, 26 can be operated in the vertical direction by being gripped by the operator M. The gripping portions 26, 26 can be configured to be foldable as necessary. The gripping portions 26, 26 are preferably configured to be foldable upward, for example, when stored in the loading platform 2A. Thereby, the protrusion of the gripping portions 26, 26 from the loading platform 2A is suppressed.

[0035] As shown in FIG. 2, the support portion 30 includes a support frame 31 assembled in a substantially rectangular shape, a pair of biasing portions 32, 32, and the like.

[0036] The support frame 31 is supported so as to be rotatable in the vertical direction with respect to the horizontal cross bar 22B. Specifically, a pair of rotating members 33, 33 along the horizontal cross bar 22B are supported at the middle portion of the support frame 31, and the rotating members 33, 33 are supported so as to be rotatable with respect to the horizontal cross bar 22B. Thereby, the support frame 31 (support portion 30) can rotate in the vertical direction around the rotating members 33, 33. The support frame 31 can freely rotate between a horizontal state stored in the carriage portion 20 and a standing state in which it stands on the ground G by being deployed (rotated) toward the ground G.

[0037] The support frame 31 can be stored between the side frames 21, 21 in the cart unit 20 by being set in a horizontal state. Further, the support frame 31 can be made to stand on the ground G by being deployed toward the ground G in a state where the cart unit 20 is moved (pulled out) until it reaches outside the loading platform 2A. Thereby, the support frame 31 can support the cart unit 20.

[0038] As shown in FIG. 3, in the present embodiment, the pair of biasing portions 32, 32 are constituted by a pair of damper members (also referred to as damper members 32, 32) having cylinders 32A, 32A and pistons 32B, 32B. The damper members 32, 32 are supported on both sides in the width direction of the support frame 31. Therefore, the damper members 32, 32 are configured to be deployed toward the ground G and stand on the ground G as the support frame 31 rotates toward the ground G. In the standing state, the pistons 32B, 32B of the damper members 32, 32 are supposed to protrude toward the ground G. Further, a base plate 34 is rotatably mounted in the vertical direction along the width direction of the damper members 32, 32 on the protruding end side of the pistons 32B, 32B of the damper members 32, 32.

[0039] The base plate 34 is provided with a pair of feet 35, 35 (see FIG. 1) that come into contact with the ground G on the back surface side (ground G side). A lock portion 36, which will be described later, is provided on the front surface side (upper surface side) of the base plate 34.

[0040] Further, the damper members 32, 32 can apply a biasing force in the direction from the ground G toward the cart unit 20 in a state where the support frame 31 stands on the ground G. That is, the damper members 32, 32 can bias the cart unit 20 on which the load 3 is loaded upward. Note that the biasing force of the damper members 32, 32 is set to such an extent that the cart unit 20 on which the load 3 is loaded can be pushed upward.

[0041] Here, as shown in FIGS. 2 and 4, the carriage part 20 can push down the support part 30 below the vehicle 2 against the biasing force of the damper members 32, 32 in a state of protruding outside the loading platform 2A. That is, the damper members 32, 32 are compressed by the weight of the carriage part 20 and the pushing down of the carriage part 20 by the operator M, and the pistons 32B, 32B contract.

[0042] The locking part 36 is configured to hold the support part 30 in a state of being pushed down below the vehicle 2 via the carriage part 20 in a state where the carriage part 20 protrudes outside the loading platform 2A. Specifically, the locking part 36 is configured to fix the damper members 32, 32 compressed by the pushing down of the carriage part 20 in a compressed state against the biasing force.

[0043] Although not shown, the locking part 36 is composed of, for example, a hook or the like biased by a spring or the like and a locking member for locking the hook, and the lock can be released by operating a switch (for example, operating with the foot of the operator M). On the other hand, when the support part 30 is pushed down by a predetermined amount, the hook of the locking part 36 is automatically locked to the locking member to be in a locked state. The locking part 36 can release (release) the compressed state of the damper members 32, 32 by releasing the lock. That is, when the locking part 36 is released, the damper members 32, 32 can be switched to a state where they can exert the biasing force. Thereby, as shown in FIGS. 3 and 5, the carriage part 20 is pushed up by the biasing force of the damper members 32, 32 and is made in a substantially horizontal state. In this way, the loading device 1 of the present invention can easily lift the carriage part 20 on which the load 3 (drone 3) is loaded by utilizing the biasing force of the damper members 32, 32 (biasing parts 32, 32).

[0044] When the carriage part 20 is in a horizontal state, it can move along the rails 11, 11 of the carriage part 20. Therefore, the operator M can grasp the gripping part 26 and move the carriage part 20 toward the loading platform 2A. Thereby, the load 3 is stored on the loading platform 2A via the carriage part 20.

[0045] Here, in the present embodiment, on the loading platform 2A, an article storage portion 4L is provided on one side (left side in the width direction) of the rails 11, 11 in the width direction, and an article storage portion 4R is provided on the other side (right side in the width direction). Hereinafter, when there is no need to distinguish between the article storage portion 4L and the article storage portion 4R, they may each be referred to as the article storage portion 4. The article storage portion 4L can accommodate (load), for example, the driving battery of the drone 3. Further, in the present embodiment, the article storage portion 4R is formed of a plurality of storage boxes (see FIG. 1), and can accommodate, for example, agricultural chemicals and fertilizers sprayed by the drone 3 and spare parts for maintenance of the drone 3.

[0046] The above is an embodiment of the loading device 1 of the present invention. Next, the operational effects achieved by the loading device 1 of the present invention will be described below.

[0047] The above-described loading device 1 has the following characteristic configurations (A) to (J). Therefore, the loading device 1 of the present invention can achieve unique effects that cannot be achieved by the following prior art.

[0048] (A) The loading device 1 of the present embodiment includes a guide portion 10 installed on the loading platform 2A of the vehicle 2, a carriage portion 20 that moves along the guide portion 10, and a support portion 30 that is housed in the carriage portion 20 and stands on the ground G by expanding toward the ground G in a state where the carriage portion 20 is moved until it reaches outside the loading platform 2A, and supports the carriage portion 20.

[0049] Since the above-described loading device 1 is configured such that the carriage unit 20 moves along the guide unit 10 installed on the loading platform 2A, the load 3 loaded on the carriage unit 20 can be arranged at a required position on the loading platform 2A along the guide unit 10. Therefore, for example, even in the case of a large article such that the load 3 occupies a large part of the loading platform 2A, after lifting the load 3, it can be moved, for example, back and forth on the loading platform 2A. Further, the above-described loading device 1 can support the carriage unit 20 by standing the support unit 30 on the ground G by expanding it toward the ground G in a state where the carriage unit 20 is moved until it reaches outside the loading platform 2A. Therefore, the above-described loading device 1 can easily transfer the load 3 onto the loading platform 2A via the carriage unit 20 even when loading a heavy load 3 onto the loading platform 2A. Accordingly, the above-described loading device 1 can perform the loading and unloading operations in one operation even for a heavy load 3. Further, since the above-described loading device 1 can store the support unit 30 in the carriage unit 20, it does not interfere with the load 3 on the loading platform 2A. Furthermore, since the above-described loading device 1 can expand the support unit 30 toward the ground G outside the loading platform 2A, the support unit 30 can function as a support leg of the carriage unit 20 during the loading and unloading operations. Therefore, the above-described loading device 1 does not need to be provided with another drive source, and thus can be configured with a simple structure, enabling cost reduction.

[0050] (B) The loading device 1 of the present embodiment is characterized in that the support unit 30 includes a biasing unit 32 that applies a biasing force in a direction from the ground G toward the carriage unit 20 in a state where the support unit 30 stands on the ground G.

[0051] Even when the support part 30 is pushed downward (toward the ground G side) and inclined due to the weight of the carriage part 20 on which the load 3 is loaded, the carriage part 20 is pushed upward by the biasing force of the biasing part 32 in the above-described loading device 1. Therefore, even when a heavy load 3 is loaded on the carriage part 20, the above-described loading device 1 can lift the load 3 to the height of the loading platform 2A without burdening the operator M. Here, various biasing means can be used for the biasing part 32, but it is desirable to use a damper member, a spring, etc. that are low in cost and do not have a separate drive source.

[0052] (C) In the loading device 1 of the present embodiment, the support part 30 includes at least one damper member 32 having a cylinder 32A and a piston 32B. The carriage part 20 includes a rotating part 25 that is rotatably supported with respect to the guide part 10 in a state of protruding outside the loading platform 2A, and a lock part 36 that holds the support part 30 in a state of being pushed downward below the vehicle 2 via the carriage part 20 in a state of protruding outside the loading platform 2A.

[0053] With such a configuration, the above-described loading device 1 can hold the damper member 32 provided in the support part 30 by the lock part 36 in a state of being pushed downward via the carriage part 20 below the vehicle 2. That is, since the above-described loading device 1 can hold the damper member 32 in a state of being pushed downward by the weight of the carriage part 20 (load 3), the carriage part 20 can be lifted using the biasing force of the damper member 32 by opening the lock part 36. Therefore, according to the above-described loading device 1, the operator M of the loading and unloading work can load the load 3 onto the loading platform 2A in one operation. Further, in the above-described loading device 1, since the damper member 32 provided in the support part 30 is composed of a cylinder 32A and a piston 32B, it can be configured without using other drive sources (for example, a motor or a pump). Therefore, the above-described loading device 1 can be configured with a simple configuration, and cost reduction is possible.

[0054] (D) The loading device 1 of this embodiment is characterized in that the carriage part 20 is provided with a gripping part 26 on the protruding end side from the loading platform 2A.

[0055] With such a configuration, the above-described loading device 1 can perform operations related to pushing down or lifting the carriage part 20 via the gripping part 26 (for example, an operation handle). Therefore, the above-described loading device 1 can improve the operability by the operator M. Here, the gripping part 26 may be configured to be foldable and storable, for example. Thereby, when the carriage part 20 is moved onto the loading platform 2A, the loading device 1 can widen the storage space of the loading platform 2A by folding the gripping part 26, and can also prevent the gripping part 26 from protruding outside the loading platform 2A.

[0056] (E) The loading device 1 of this embodiment is characterized in that the carriage part 20 is provided with a rotation support part 23 for rotating the load 3 mounted on the carriage part 20.

[0057] With such a configuration, the above-described loading device 1 allows the operator M to load the load 3 onto the carriage part 20 without worrying about the loading direction of the load 3. That is, after loading the load 3 onto the carriage part 20, the above-described loading device 1 can freely rotate the load 3 via the rotation support part 23, so that the burden on the operator M of reloading the load 3 can be reduced.

[0058] (F) The loading device 1 of this embodiment is characterized in that an article storage part 4 is provided on one side or both sides in the width direction of the guide part 10 on the loading platform 2A.

[0059] With such a configuration, the above-described loading device 1 can effectively utilize the storage space of the loading platform 2A. Here, examples of the stored items stored in the article storage part 4 include the load 3, and when the items are devices (for example, agricultural machines and drones), drive batteries, agricultural chemicals, fertilizers, etc.

[0060] (G) The loading device 1 of the present embodiment is characterized in that the support portion 30 is rotatably supported with respect to the carriage portion 20.

[0061] With such a configuration, the above-described loading device 1 can rotate the support portion 30 to a predetermined angle (for example, the vertical direction) according to the inclination of the carriage portion 20. Further, the above-described loading device 1 can be stored in the carriage portion 20 by rotating, for example, in the direction along the carriage portion 20.

[0062] (H) The loading device 1 of the present embodiment is characterized in that the load 3 mounted on the carriage portion 20 is a drone 3.

[0063] With such a configuration, the above-described loading device 1 can load, for example, the drone 3 used in agricultural operations such as pesticide spraying and fertilizer spraying onto the loading platform 2A of a light truck or the like in one operation. Therefore, the above-described loading device 1 can be easily used and provided at a low cost even in fields such as agriculture where a shortage of manpower is being called for.

[0064] The above is the configuration and operation and effects of the embodiment of the present invention. However, the loading device 1 of the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention.

[0065] In the present embodiment, a light truck is exemplified as the vehicle 2. However, various vehicles can be used as the vehicle 2. For example, the vehicle 2 may be a small, medium, or large truck, or a van equipped with a loading platform 2A. Further, in the present embodiment, the guide portion 10 (rails 11, 11) is provided along the front-rear direction of the loading platform 2A. However, the direction in which the guide portion 10 is provided can be arranged in various directions according to the loading platform 2A. For example, the guide portion 10 may be provided along the width direction of the loading platform 2A. In such a case, the carriage portion 20 (load 3) may be loaded from one side or the other side in the width direction of the loading platform 2A.

[0066] In addition, the cart unit 20 is not limited to the present embodiment, and those of various shapes and sizes can be used. If necessary, a loading portion for the loaded object 3 may be provided. Further, in the present embodiment, in a state where the cart unit 20 is moved until it reaches outside the loading platform 2A, the support portion 30 is configured to deploy toward the ground G. However, the timing at which the support portion 30 deploys may be such that it is performed before the cart unit 20 completely reaches outside the loading platform 2A. In such a case, it is desirable that the support portion 30 be deployed at a timing when the support portion 30 and the loading platform 2A do not interfere with each other. Further, in the present embodiment, an example is shown in which the support portion 30 stands upright with respect to the ground G. However, the standing state of the support portion 30 may not be limited to an upright state, and may be an inclined state.

[0067] In the present embodiment, a damper member 32 is used as the biasing portion 32. However, as the biasing portion 32, various biasing members capable of exerting a biasing force capable of lifting the cart unit 20 can be used. For example, the biasing portion 32 may be constituted by a spring. Further, the damper member 32 is not limited to those having a cylinder 32A and a piston 32B, and various dampers can be used. Further, the biasing portion 32 (damper member 32) is not limited to two, and a single one or three or more may be provided. Further, as the damper member 32, for example, a damper used for a back door of an automobile or the like can be used. Further, the biasing force of the biasing portion 32 can also be appropriately changed according to the weight of the cart unit 20, the loaded object 3, and the like. For example, the biasing force of the biasing portion 32 is not limited to only that which can lift the loaded object 3, and may be such that it can assist the work of the operator M (for example, to such an extent that the burden on the operator M can be reduced). Further, the direction in which the biasing force is exerted by the biasing portion 32 may be appropriately changed according to the lifting direction of the cart unit 20.

[0068] In addition, various means can be used for the locking portion 36, and the location where the locking portion 36 is provided and the like can be changed to various locations according to the mechanism of the locking portion 36 and the like. For example, a locking mechanism used for a back door or a bonnet of an automobile can be used for the locking portion 36. Further, the rotating portion 25 provided on the cart portion 20 is not limited to being rotatable, and various means such as a fixed type or a type that can switch the inclined state of the cart portion 20 step by step can be used. That is, the rotating portion 25 may be provided as necessary, and a configuration without the rotating portion 25 can also be adopted.

[0069] In this embodiment, an example is given in which the cart portion 20 includes the gripping portion 26, but the gripping portion 26 may be provided as necessary, and a configuration without the gripping portion 26 can also be adopted. Further, when the gripping portion 26 is provided, the shape, size, etc. of the gripping portion 26 can be changed to various types. Further, the gripping portion 26 is not limited to a fixed type, and may be a foldable type or a detachable type. Further, the gripping portion 26 may be configured by being coated with an appropriate rubber, resin, or the like.

[0070] In this embodiment, the cart portion 20 includes the rotation support portion 23, but when it is not necessary to rotate the load 3, a configuration in which the rotation support portion 23 is excluded can also be adopted. Further, the rotation support portion 23 may be rotated by an appropriate drive source such as a motor in addition to manual rotation, but from the viewpoint of cost reduction, it is desirable to use a manual one.

[0071] In this embodiment, the article storage portions 4L and 4R are provided. However, the article storage portions 4L and 4R may be provided as necessary, and either one or both of the article storage portions 4L and 4R may be omitted. Further, in this embodiment, the support portion 30 is rotatably supported with respect to the cart portion 20. However, the loading device 1 of the present invention is not limited to this. For example, the support portion 30 may be fixed to the cart portion 20. For example, the support portion 30 may be fixed in a deployed state, or the support portion 30 may be accommodated in the cart portion 20 by bending or the like. Further, the shape, size, quantity, stored items, etc. of the article storage portions 4L and 4R can be changed into various forms.

[0072] In this embodiment, the case where the load 3 mounted on the cart portion 20 is the drone 3 is illustrated. However, the loading device 1 of the present invention is not limited to the drone 3, and various loads 3 can be loaded. For example, the loading device 1 of the present invention can be used for loading and unloading various loads 3 such as agricultural machines, vehicle parts, various devices, tools, and wheelchairs. Further, the drone 3 is not limited to an agricultural one, and various drones can be used.

[0073] The above are various embodiments and modifications of the loading device according to the present invention. However, the present invention is not limited to those illustrated in the above-described embodiments and modifications, and it will be easily understood by those skilled in the art that there may be other embodiments within the scope not departing from the teachings and spirit of the claims.
